(Closed) BBQ to celebrate my wedding, Help with the invitations!

Hi im from Chile and my fiance is american. We will have the wedding in my country, and for that reason not everybody from his family and friends can make the travel. Thats why we decided to make a BBQ in his parents backyard to celebrate with everybody here in the USA.

I need some help with the text of the invitation. I dont have any idea how I can start it.
